Rare earth-based titanium tungsten powder special for de-nitration catalyst is the core technology of novel no vanadium rare earth-based titanium tungsten de-nitration catalysts specifically developed for traditional titanium tungsten vanadium de-nitration catalyst by our company, and also the center of reaction principle of de-nitration catalyst, which means adsorption-activation-reaction-de-sorption. As the center of catalytic activity of de-nitration catalyst, ReO2 is the catalytic active center and its rational distribution and dispersion amount directly determine the dispersion degree and amount of catalytic activity center, which are the bases of temperature transition and service time of catalysts.
Used in the area of exhaust system of large utility boilers, industrial boilers, and municipal solid waste boilers and have been shown to reduce NOx by 92-95%. More recent application include diesel engines, such as those found on large ships, diesel locomotives, gas turbines, and even automobiles.
